WASTE PIPE CLEANER- Filed April 18, 1929 Inventor Aitorney Patented Mar. 17, 1931 PATENT OFFICE ALFRED NOWAKOWSKI, OF MILWAUKEE, WISCONSIN WASTE-PIPE CLEANER Application filed April 18,

This invention relates to a waste pipe cleaner, and more especially to a device for clean ing sink waste pipes.

A further object of this invention is to provide means for cleaning waste pipe by flushing the same with water taken from the house supply spigot, and at the same time permitting use of the conventional cleaning organ now in use.

Another very important object of my invention is to provide a device of the character above described which will be simple in construction, inexpensive, quickly and easily assembled, practical and efficient in operation.

The above and numerous other objects and advantages of the invention will become ap parent during a study of the following description taken in connection with the accompanying drawings, wherein:

Figure 1 is a side elevation of my improved sink waste pipe cleaner and illustrates the use in connection with sinks and applied thereto.

Figure 2 is a longitudinal sectional view taken through my improved cleaning device. 25 lVit-h reference more in detail to the drawings it will be seen that the numeral 5 designates a conventional kitchen sink, having the usual water spigot or faucet 6, associated therewith in the usual manner. The reference character 7 designates the pipe coupling extended inwardly of the wall 8 to which the conventional drain pipe ofthis'sink is fixed in the ordinary manner. I lVhen it is desired to clean the'waste pipe 7, the drain pipe leading-from the sink 5 is removed therefrom and my improved cleaning device may then be brought into operation.

As illustrated in the drawings, my improved device comprises a body portion 9 which consists of an open ended pipe 10, the open end of said pipe being internally threaded as at 11 to receive the extension nipple 12 provided with the Vcomplernental threads 13 for connecting the nipple to the open end of the pipe 10. The other end of certain detail structural features and adthe nipple 12 is provided with external threads 14: and is screw threaded into the pipe 7 as at 15. The opposite end of the body portion 9 is provided with a reduced extension 1929. Serial No. 356,138.

16, which extension 16 has a longitudinal bore 1? extending therethrough, while the conventional steel spring clean-out auger 18 has its handle portion 19 extending through the bore 1? in the extension 16 as illustrated in the drawings, This auger 18 is of the conventional type and is best'known by plumbers as a sink rod.- The pipe portion 10 of the body 9 is provided with a Y-extension 20 while a flexible hose 21 has one end secured to the Y-pipe 20 by means of the conventional hose coupling 22 and the other end of the flexible hose 21 being connected by means ofthe flexible hose coupling 23, to the spigot 6. Attention is also called to the fact that the free end of the extension 16 has the bore 17 terminating adjacent the end of the extension in a relatively wider portion to permit a packing 2a to fit about the handle 19 of the sink rod, while a cap 25 is threaded to the end of the extension 26 to hold the packing tight within the recess and against the handle to provide a water tight packing.

When the device is connected as has just been explained and described the spigot 6 is turned on to permit the flow of water through the flexible pipe 21 into the body 9 and thence through the waste pipe 7. By turning the handle on the auger, all of the grease and V dirt that sticks to the pipe of the waste running through the pipe is loosened and consequently washed down through the pipe 7 through the sewer by the force of the water from the spigot, thus leaving the pipe thoroughly cleansed and free from whatever waste mayhave collected.

From the foregoing it will be seen that I have provided an improved cleaning device especially adaptable for waste pipes of sinks, basins and the like and which is composed of but few parts, is simple in construction, may be easily assembled with the waste pipe and the water passage of the basin, sink or the like, and is thoroughly eificient and practical in use.

7 While I have herein shown and described vantages of my invention, it is to be understood that certain changes may be made therein without departing from the spirit of the invention as described or the scope of the appended claim.

I claim:

In a device for cleaning waste pipes, and in combination, a body portion comprising a pipe of relatively large diameter open at one end and at its other end terminating in an elongated reduced extension, having a bore extending therethrough and communicating with the pipe, a nipple having one end thereof threaded in the open end of said pipe and its other end threaded in the waste pipe to afford communication between said waste pipe and said body, a Y-extension formed on said body and communicating with the interior of said pipe forwardly of said reduced extension, a flexible hose secured at one end to said Yextension and having its other end adapted to be secured to the outlet portion of a supply pipe, a cleaning auger arranged in said body for passing through said nipple into the waste pipe, said auger having an elongated handle rotatably and slidably receivable in thebore of said reduced extension, packing arranged in the free extremity of said reduced extension, and a cap threaded on said free extremity and having an open ing' formed therein through which the free end of said handle extends.

In testimony whereof I aiiix my signature.
